Improvement in machinery for cleaning emery-wheels



UNITED STATES JOHN CHANDLER, OF COLLINSVILLE, CONNECTICUT.

IMPROVEMENT IN MACHINERY FOR CLEANING EMERY-WHEELS.

Specication forming part of Letters Patent No. 34,104, dated January1862.

To all whom t may concern:

Be it known that I, JOHN CHANDLER, of Collinsville, in the county ofHartford and State of Connecticut, have invented a new and usefulMachine for Cleaning Emery-Vheels; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings, making a part of this specification,in Which- Figure l is a longitudinal vertical section of my invention,taken in the line o: fr, Fig. 2; Fig. 2, a transverse vertical sectionof the same, taken in the line y y, Fig. 1; Fig. 3, a horizontal sectionof a portion of the same, taken in the line z z, Fig. 2.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of this invention is to obtain a simple machine to supersedethe manual process of cleaning emery-Wheels which are Worn and requireto be re-coated. The ordinary manual process is attended With aconsiderable expenditure of time and labor, and the emery which isremoved from the Wheels is Wholly lost. By my invention, hereinafterdescribed, the emery which is removed from the wheels is all saved andmuch labor avoided.

The invention consists in placing one or more sliding frames on verticclguide-rods, said frames having the Wheels Which are to be cleaned tittedin them and allowed to rotate freely, and using, in connection With saidframes, a Water box or tank, Which is provided with a roller or rollers,all being arranged to operate substantially as hereinafter described toeffect the desired result.

To enable those skilled in the art to fully understand and construct myinvention, l will proceed to describe it.

A represents a horizontal bed-piece, Which may be supported at asuitable height by legs or a framing, and B is a Water box or tanksecured longitudinally on the bed-piece A, and extending nearly itsWhole length. On the upper part of the box or tank B there are placedrollers C, one or more. Three rollers are shown in Fig. 1,Which areparallel with each other and are placed transversely on the box or tankB. The shafts ct of the rollers C have pulleys b on them at one end andat the outer side of the box or tank B, said pulleys having belts cpassing around them, so that the three rollers Will be rotatedsimultaneously by applying power to any one of them.

D represents vertical guide-rods, which are attached to the bed-piece Aat each side of the box or tank B, there being as many rods D at eachside of the box or tank B as there are rollers C. The rods D areconnected at their upper ends by transverse bars E and longitudinal barsF.

O11 the rods D there are fitted frames E', Which have a transverseposition with the bed-piece A and box or tank B. These frames areallowed to slide freely up and down on the rods D, and to the lower partof each frame E there are secured two bearings d CZ, in which centerrods c are placed to receive the ends of the mandrels f of the Wheels Gto be cleaned. The rods e are secured in their bearings d by set-screwsg, and when the device is in operation the peripheries of the Wheels Gare in contact With the rollers C.

'The frames E are counter-poised by Weights H, the cords It of whichpass over guide-pulleys t' in the bars E, and are attached to thecenters of the frames. These Weights H prevent the Wheels G from restingtoo heavily on the rollers C, and at the same time facilitate theelevating Aof the frames E to admit ot' the Wheels G being adjusted inand romoved from the frames E. 1When the frames E are thus elevated forthat purpose, they are secured by set-screws j. (See Figs. 2 and 3.) Therollers C may be of Wood covered With leather; but other materials mightbe used.

The operation is as follows: The box or tank B is supplied with Water,either hot or cold, the Water being sufficiently high to cause the lowerpart of the rollers C to be submerged. Any one of the rollers C isrotated by any convenient power, and the Wheels G, having been adj ustedproperly in the .frames E', rest on the rollers C and are rotated bythem. The emery on the peripheries of the Wheels G is thereby moistenedand subjected to suficient rubbing or friction to insure its detachmentfrom the Wheels, and the emery settles in the box or tank B. When theWheels G are all cleaned, the frames E are elevated and secured in suchposition by the screws j. The Wheels G are then removed from the framesE by sliding` back one of the center rods e of each frame, and otherWheels which are to be @leaned are inserted in their places.

By this invention einery-wheels may be cleaned very expeditiously and ina perfect manner and all the emery which is removed from the Wheelssaved for further use.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The employment or use of a Water box or tank B, supplied with one ormore rollers C, in combination With one or more sliding frames E forholding the Wheels G to be cleaned, all being arranged substantially asand for the purpose set forth.

JOHN CHANDLER.
